I also have had Puppy hang on selecting SHUTDOWN from the menu.
To continue the shutdown, I have found that it will finish the shutdown if I do an ALT-CTRL-Backspace key combination.
So it sounds like the xwin manager is not being shut down properly and the key combination manually does that step to allow the shutdown to continue.

Some Puppies have a bug where the attempt to kill processes using a partition leads to kill the shutdown process(es) (rc.shutdown, poweroff | reboot) themselves . This leads to this situation . Better unmount everything before poweroff . Another attempt might be replacing

lines 548-550 contain slightly different text, but seem to match the idea. Do I just edit the text in this file or go further, and which line should I change pls, as at least 2 contain similar statements, & I'm a noob. thx, btw is 551 "if"?
What is meanining of "do not use fuser if network share mount"? How do I tell if this is the case?

I do wish ppl would use English, where possible, rather than Geekese, which seems to have too many variant dialects for good understanding. C++ is not that hard, until ppl start their own dialects. Then understanding for beginners becomes too difficult, I fear it's often deliberate to force payment for service, which is an immoral backdoor act, that the customer should have been warned of before he got the product.

When I was a kid I wanted to be older.... This is not what I expected

thx for persisting, I hope we get it eventually. What else are you likely to need to know? nb there is a very fast orange msg at the end of some text after I select shutdown. I have no way of freezing my screen or capturing it. it is followed by the msg that the computer is shutting down,then saving session to sda.

Then it might be that your are running frugal with "Save to entire partition" . Try "Save to a save file" instead . There are several remarks atm that this does not shutdown correctly . I personally have never used an installation to USB flash with "Save to entire partition" mode .

how do I tell if it's frugal? there's no advisor saying what is saving, though it does take some time [4GB Verbatim USB 2.0] Was installed as superfloppy.where do I make that change, pls?
further, when attempting to install other addons etc nothing works-testing url's show recursion disabled! download not possible.
